Description: This object gives the packetization period for a particular codec. for G.711u allowed values are 10 & 20 for G.711a allowed values are 10 & 20 for G.726 at 32 kbps allowed values are 10, 20, 30 & 40 for G.729a allowed values are 10, 20, 30 & 40 for G.729ab allowed values are 10, 20, 30 & 40 for clear channel allowed values are 10 and 20 for G.726 at 16 kbps allowed values are 10, 20, 30 & 40 for G.726 at 14 kbps allowed values are 10, 20, 30 & 40 for G.726 at 40 kbps allowed values are 10, 20, 30 & 40 for G.723 allowed values are 30 & 60 for Lossless allowed values are 10 and 20 Default value for G.723 is 30, for other codecs it is 10.
What is vismCodecPktPeriod?
This read-write INTEGER object, in milliseconds (values ten through sixty), sets the packetization period for a particular codec, with the specific allowed values varying per codec (e.g., G.711u/G.711a allow only 10 and 20, while G.726/G.729/G.729ab allow 10 through 40). Since packetization period trades latency against per-call bandwidth overhead, and each codec has different valid ranges, this setting must respect the codec-specific constraints to be accepted. An engineer trying to squeeze more calls onto a bandwidth-limited G.729a trunk would raise this period toward the codec's allowed maximum rather than assume all codecs share the same range.
